Be sure to read and comply with the instructions contained within this Service Bulletin prior to installing transient voltage suppressors.

Introduction:

This Service Bulletin describes the addition of transient voltage (or contact) suppressors whenever the Solid State Relay (SSR) output in the User Connection Bay Extended (UCBE or UCBEE) is connected to an external circuit containing relay coils, contactor coils, or motors.

These transient voltage suppressors are necessary and essential REGARDLESS of the voltage level at the device connected to the SSR output.

Notice that the SSR outputs are limited to 100 milliamps on AC circuits and to 50 milliamps on DC circuits.

Affected:

All Capstone MicroTurbine installations that use the SSR outputs for various functions are affected.
